RIP emplea temporizadores para mejorar surendimiento.►Routing-update timer Inicialmente 30 seg. Intervalo entre las actualizaciones de tabla de enrutamiento.
►Route-timeout timer ó Hold down en 180 seg. Cada entrada tiene un route-timeout asociado. Cuando expira, la ruta es señalada como inválida y la métrica se configura con 16; pero no es borrada de la tabla de enrutamiento.
►Route-flush timer Inicialmente en 240 seg Cuando expira el route-timeout, se borrará la entrada de la tabla de enrutamiento cuando expira el route-flush timer.
Comando: Indica si el paqueteRIP es de requerimiento orespuesta.►Requerimiento (1) pregunta a un router por el envío total o parcial de su tabla de enrutamiento.
►Respuesta (2) puede ser una actualización de enrutamiento no solicitada o en respuesta a un requerimiento.
Version: Indica versión delprotocolo RIP. Está en 1.Métrica
Address Family IdentifierAFI.►Especifica la familia de dirección usada. RIP está diseñado para llevar información de enrutamiento de varios tipos de protocolos.
Dirección IP: Indica la dirección IP de entrada.
►AFI está en 2 para IP.
Métrica: Indica cuantosrouters atraviesa RIP.►El valor está entre 1 a 15.
RIPv2Comando: Indica si el paqueteRIP es de requerimiento orespuesta.
Version: Indica la versióndel protocolo RIP.
Address Family IdentifierAFI.►Es similar al RIPv1, con una excepción►Si el AFI de la primera entrada está en FFFFh, el resto de las entradas contiene información de autenticación.

OSPF origina que cada routers conozca de maneracompleta toda la red de su área.
Campo Longitud del paquete:► Indica longitud del paquete OSPF, incluyendo la cabecera OSPF.
Campo ID del Router:► Indica el ID del router que originó en paquete OSPF. Normalmente cada router escoge como ID la IP mayor entre las IP activas y la loopback si esta está activa.
Campo ID del Área:► Indica el área en el que se originó el paquete OSPF.
Campo Suma de Chequeo:► Verifica todo el contenido del paquete OSPF, excluyendo el campo de autenticación.Campo Tipo de Autenticación:► Indica el tipo de autenticación a usar en el paquete. Se configura por áreas. La RFC 2328 define dos tipos de autenticación: - 0 Ninguna - 1 Password de 64 bits, texto. - 2 Autenticación MD5.Campo Autenticación:► Campo de 64 bits, contiene la información de autenticación.

Campo de Router Designado (DR):► Identifica a un router dentro de un sistema autónomo. Es la dirección IP más alta de sus interfaces. Es utilizado para seleccionar el router DR.Campo de Router Designado de Respaldo (BDR):► Selecciona el router BDR (cuando no escucha LSA desde el DR)Lista de vecinos► Enumera la ID del router OSPF de los routers vecinos.
Definición de Identificador de Router (ID-Router):► Al iniciarse el proceso OSPF en un router, el IOS utiliza la dirección IP activa local más alta como ID del router.► Si no existe una interfaz activa, el proceso OSPF no se iniciará.► Para asegurar la estabilidad del proceso OSPF, es necesario que el router tenga una interfaz activa en todo momento.► La interfaz loopback es importante para este objetivo.
En un router con más de una interfaz loopback,la dirección más alta será el ID-Router.
Selección del Router Designado (DR):► La interfaz con mayor prioridad permitira el router sea DR.► Ante iguales prioridades se selecciona el de mayor ID-Router.
